Alonzo is dashing and debonair, with a large measure of Latin flair.

Rarely used, and for good reason. Alonzo is a preferable choice.

Alonso is the Spanish and Portuguese diminutive version of Alfonso, itself deriving from an old Germanic name "Adalfuns" meaning "noble and ready." Although the Italian spelling Alonzo is more popular in the US, Alonso has its own strong history.

Alfonso was a royal name in Spain as far back as the 7th century, but it is rarely heard outside the Hispanic community in the US.

For older generations this still summons silent horror star Chaney; for others it's a pleasant if slight nickname name.

This Latinized form of a name that's well used in Italy and Spain is sometimes heard, oddly enough, in Ireland.

The M and the R add welcome strength.

Adds some dash and substance to Lon.
